Exploiting many-body localization for scalable variational quantum simulation
Chenfeng Cao, Yeqing Zhou, Swamit Tannu +2
Variational quantum algorithms (VQAs) represent a promising pathway toward achieving practical quantum advantage on near-term hardware. Despite this promise, for generic, expressiv…
Statistical characterization of valley coupling in Si/SiGe quantum dots via -factor measurements near a valley vortex
Benjamin D. Woods, Merritt P. Losert, Nasir R. Elston +5
The presence of low-energy valley excitations in Si/SiGe heterostructures often causes spin qubits to fail. It is therefore important to develop robust protocols for characterizing…
Warm Start Adaptive-Bias Quantum Approximate Optimization Algorithm
Yunlong Yu, Xiang-Bin Wang, Nic Shannon +1
In the search for quantum advantage in real--world problems, one promising avenue is to use a quantum algorithm to improve on the solution found using an efficient classical algori…
g-factor theory of Si/SiGe quantum dots: spin-valley and giant renormalization effects
Benjamin D. Woods, Merritt P. Losert, Robert Joynt +1
Understanding the -factor physics of Si/SiGe quantum dots is crucial for realizing high-quality spin qubits. While previous work has explained some aspects of -factor physics…
